"iThis invention relate generally to air outlet devices for=ventilatingsystems, 'andhas particular reference to improvements means for mountingin thenecks of 'such devices" adjustable air deflecting units for usepredetermining the pattern of the air deliveredfrom such devices.Generally speaking, the object of the invention isto provide simple,practical means to facilitate mounting ofan air deflecting unit in theneck of any air outletdevice and to'enable ready and easy removal of theunit from theneck whenever desired for cle aning, adjustment or anyother purpose. y I

An adlustableair defle'ctingunit' of the t pe with whichtheipresentinvention is concerned 'co mprises'a band or'ring and a plurality ofvanes extending across the same and p'ivotedthereto for adjustments todesired air deflecting angles relative to the band or ring and relativeto each other. In this connectiona more specific object of the inventionis to provide in the neck of an air outlet device, mounting means for anadjust- .able air deflecting unit'of the type mentioned, which mountingmeans is in the form of-spring arms with which the ringorband ofthe airde- 7 fleeting unit may readily and easily be engaged to operativelymount said unit in said neck and from which said band or, ring-mayreadily and easilybe disengaged to permit removal of the air deflectingunit whenever desired. A well known type of air" outlet livering airfrom an air supply duct into a room or other enclosure for heating,cooling, ventilatingorother purposes compris s a plurality ofsucessively smaller, open-ended, hollow, flaring members which arespaced apart successively inwardly of one'another and the larger oroutermost'of which-is provided at its smaller or rear end'with a neckforconnection with an air supply du'ct;- "Thus, air supplied to-the devicethrough the neck thereof is divided by the flaring members into aplurality of separate'streams which are deflected more or less laterallyoutward from the device, by said membersand the ,air thereby isdelivered from the device in diffused form. In an air outlet device ofthis type it is known to connect together as a unitary assembla e allexcept the outermost ofthe flaring members and to provide means to mount'saidunitary assemblage in the lar er or outermost flaring member forready removal therefrom to afford ready access to the neck of the largeror outermost flaring member and thus facilitate connection of said neckwith an air supply duct, as well as to fa l tate proper mounting ofthe-outlet device device for deas a whole.

aforementioned spring arms upon said unitary assemblage of flaringmembers so that when the latter is removed from the larger or outermost,flaringmernber an air deflecting unit may readily and easily be engagedwith said spring arms for subsequent operative positioning in the neckof the device by the mere act-of mounting said unitary assemblage intheiarger or outermost flaring member, and so that "in the event an airdeflector is already engaged with saidarms when said unitary assemblageis removed, said air deflecting unit is removed with saidunitaryassemblage and thereby is readily accessible for cleaning, adjustment,or any other purpose. Further in this connection, another object of theinvention is to mount the said spring arms upon the struts or bars whichusually are employed to connect together the flaring members of theunitary assemblage and to rem ovably mount said assemblage in the largeror outermost flaring member, whereby the said spring arms are firmly andsecurely mounted upon said unitary assemblage.

With the foregoing and other objects in View, as will become more fullyapparent as the nature of the invention is better understood, the sameconsists in the provision of means for the purpose embodying the novelfeatures of construction, combination and arrangement of parts as areillustrated by way of example in theaccompanyin drawings and as will behereinafter more fully described and claimed.

Refe r g to thie d wings in det il si e s, g ne al y. an a r Out d ic ofa kn type with whichthe present invention is concerned and Bdesignates,'generally, an air defleet n un t o a known typ f r use i ntion with an ,airoutlet device such-as the device A to predetermine thepattern of the air delivered therefrpm;

In this connection another object of the invention is to provide'formounting of the v duct, and when air is supplied to the device throughsaid neck it is divided by the members I0 into a plurality of separatestreams which flow through the passageways II and are de- I,

flected more or less laterally outward from the device by said membersID depending upon the flare of the latter. The air thereby is deliveredfrom the device in diffused form throughout a Y substantial areaforwardly and laterally relative to the device. a v

The air deflector unit B comprises a ring or band I3 of a size and shapeto be accommodated more or less freely within'the neck I2 of the outletdevice A, an a plurality ofvanes I4 extending in suitably spacedapart,'preferablyfparallel relationship to each other, from side to sideof said band and pivoted at their ends to said band, as indicated at I5,or rotative' adjustments to different angularpositions relative to eachother. The air deflector unit B is designated to be mounted in-the neckI2 of the air outlet device A, in a plane at right angles to said neck,to position the vanes I4 s o that by proper pivotal ad- ,justments ofthe same they maybe caused to deflect supplied air through desiredportions of the passageways and'thus predetermine the pattern of the airdelivered from the device A.

In an air outlet device A of the type illustrated it is known to connecttogether as a unitary assemblage all except theoutermost of the flaringmembers I0 and to provide means to removably mount said unitaryassemblage in the larger or outermost flaring member I0 to aflord readyaccess to the neck I2 for the purpose of facilitating connection of saidneck with an air supply duct and proper mountingof the device A. In thisconnection and as illustrated by way of example in the drawings, allexcept the outermost of the flaring members ID are connected together asa unitary assemblage by a plurality of bars I 6 which extend across thesmaller or rear ends of said members I0 and are welded or otherwisesuitably fastened to said members: The outer 'end portions of said barsI6 extend beyond'the larger or outermost flaring member of the unitaryassemblage and are bent to extend forwardly at angles corresponding tothe flare of the larger or outermost flaring member ID of the device Aso as to engage flatly against the front face of said larger oroutermost flaring member to determine proper positioning of theunitaryassemblage of flaring members forwardly and rearwardly relativeto said outermost flaring member Ill, More over, the terminal portionsof the bars I 6 are bent to extend at substantially right angles to saidbars in the planes of the outer end portions of said bars to providesaid bars with hook-like extremities I1 for cooperation with suitablesockets I8 with which the larger or outermost flaring member ID of thedevice A is equipped to removably mount said unitary assemblage offlaring members in said larger or outermost flaring member II). Thesockets I8 may be provided by U-shaped members I9 riveted, welded orotherwise suitably fastened against the front face of the larger oroutermost flaring member ID of the device A, as illustrated in Figs. 1,2, 3 and 5 of the drawings, or they may be provided by forwardlydepressing portions 20 of the larger or outermost flaring member II] ofthe device A as illustrated in Fig. 4 of the drawings. In any event, itisapparent that the hook-like extremities .II and the sockets I8 providemeans whereby the unitary assemblage of flaring members I0 may readilyand easily be mounted in the larger or outermost flaring member ID ofthe device A and may equally as readily be disconnected from said largeror outermost flaring member of the device A for removal therefrom,simply by a small amount of rotation of said, unitary assemblage offlaring members relative, to the larger or outermost flaring member IDof the device A. The means for removably mounting the air deflectingunit B in the neck I 2 consists of a plurality of spring armsY2I whichmay, if desired, be permanently mounted said neck, but which,preferably, are carried by the unitary assemblage of flaringmemberswhereby they are operatively positionedin therieckflIZ by mounting ofthe unitary assemblage of flaring members in. the larger or outermostflaring member of the device A and are removed from'said neck when saidunitary assemblage of flaring .members is removed from the larger oroutermost flaring member of the device A., I. a. j

If desired, the arms 2I.maybe welded, riveted or otherwise suitablyfastened to one or more of the flaring members I0 of the unitaryassemblage of said members; to the outermost of said members forexample. Preferably, however, said arms are fastened to the bars I6, asthereby they are more firmly and securely supported than would be thecase ifthey. were fastened directly to one or.more of theflaringemembers I 0. In any event, said arms extend rear'wardly from theunitary assemblage of flaringmembers whereby they are disposed in theneck. I2 and extend longitudinally thereof when theunitary assemblage offlaring members is operativelyfmounted in the larger or outermostflaring member ID of the device A. Moreover, said arms are positionedrelative to the unitary assemblage of flaringmembers so that they aredisposed more or less closely adjacent to the neck I2when'saidunitaryassemblage of flaring members is operatively mounted in thelarger or outermost flaring member of the device'A. In other words, therelationship of the arms 2| relative to each other is such that they areengageable with thering or band I3 of the air deflecting unitB at spacedpoints around said band to supportlthe latter'and, hence, said airdeflecting unit B as an entiretyin its operative position in the neck I2when the unitary assem blage of flaring members mounted in the larger oroutermost flaring memberofthe device A.

To adapt the arms 2 I to hold the air deflecting unit againstlongitudinal movement relative to said arms, said i arms' are providedwith ofi-set portions-22 wherein the ring or band I3 is accommodated andwhich afford'shoulders23 for engagement with opposite edges of saidrringor band. In this connection and as will be understood, the ring or bandI3 may be disposed either outwardly or inwardly relative to the arms 2I, and the portions 22 of said arms may be offset either inwardly oroutwardly to accommodate said rin or band, dependingupon whether thelatter is disposed outwardly or inwardly of said .arms. In any event,the arms 2I are flexible to enable ready and easy engagement anddisengagement of the guide; the ring or band -;lfi onto said arm l3 withthe aisle. and the (tre end rin or and 'edito portions; izlof' saidarmspreferably are ine'lf Fig. '14 illustrates thatfif' desires, theappeal! instead of the'bars fli, mayhave hook-like'porother'hand, Fig.illustrates that, if desired',.the

arms 2| may bepermanently fastened in and to the neck I2, in whichconnection it will be apparent that said arms may be either entirelyseparate from each other or may be carried by a ring or band as shown.'As will also be apparent, the arms M may have their free end portionsdisposed either rearwardly, as shown, or forwardly if desired.

Whether the arms 2! are mounted permanently in the neck l2 or upontheunitary assemblage ofv flaring members, it is apparent that the airdefleeting unit B is readily engageable with and disengageable from saidarms when said unitary assemblage of flaring members is removed from thelarger or outermost flaring member of the device A, whereby operativemounting of said air deflecting unit in the neck I 2 is greatlyfacilitated.

Spring fingers 26 fastened against the rear face of the larger oroutermost flaring member In of the device A and having projections 21 topass through holes in said larger or outermost flaring member into holesor depressions in the terminal portions of the bars IE or the arms 2|,as the case may be, are employed as a practical means of frictionallyholding the unitary assemblage of flaring members against rotation in adirection to disconnect said assemblage from the larger or outermostflaring member of the device A.

From the foregoing description considered in connection with theaccompanying drawings, it

is believed that the construction, operation and advantages of the meansconstituting the present invention will be clearly understood. It isdesired to point out, however, that while only certain specificembodiments of the invention have been illustrated and described, thesame is readily capable of specifically difierent embodimentsv withinits spirit and scope as defined in the ap pended claims.
